Answer

$S^(2-)(aq)+Fe^(2+)(aq)\operatorname{\rightarrow}FeS(s)$

Step-by-step explanation

The reaction is a double displacement reaction.

Step 1: Write the balanced molecular equation with the state of the substances as shown below:

$K_2S(aq)+Fe(NO_3)_2(aq)\rightarrow2KNO_3(aq)+FeS(s)$

Step 2: Split the substances into ions (ionic equations):

$2K^++S^(2-)+Fe^(2+)+2NO_3^-\operatorname{\rightarrow}2K^++2NO_3^-+FeS$

Step 3: Cancel out the spectators on both sides of the complete ionic equation in step 2.

$S^(2-)+Fe^(2+)\operatorname{\rightarrow}FeS$

Step 4: Write the remaining substances as the net ionic equation.

$S^(2-)(aq)+Fe^(2+)(aq)\operatorname{\rightarrow}FeS(s)$
